Bandit Cunning

Your time as a bandit has granted you a sense for danger, and made you skilled at sizing up opponents. You gain the following benefits:

• When you are asked to make a saving throw, you may spend your reaction to add your Intelligence modifier as an additional bonus to the saving throw. You cannot use this ability again until you have completed a long rest.

• During combat, you can use your action to make an Intelligence (Investigation) check against any creature you have seen fight. As long as you succeed against a DC of 10 + their challenge rating, you can learn one useful fact of your choice about the target’s combat abilities. Choose from:
  • one damage resistance or immunity
  • one condition immunity
  • one special ability possessed by the creature that either does damage, or prevents damage
  • one option under their attack, legendary, or reaction actions
  • one special sense they possess
